Colonialism was how slavery was created, you do know that, presumably.
Real racism, is perpetuation of colonialism. You probably know that also.
Yet, you yourself are working in the mode of colonialism.
The worst injustices against a people, I think, must surely be those carried out by their own members, effectively brainwashed or otherwise.
The only way we will stop racism, is to dismantle the hierarchy of colonialism which never went away since the first time we (original colonials) went and claimed the first country and its people as our property.
The colonialism won’t stop, as long as folks like yourself carry on demonising other countries, who you always paint as enemies, or even just as competitors.
